Abstract

The invention is applied to the technical field of photovoltaic power sources, and provides a photovoltaic module optimizer redundancy direct connection device and a control method of the photovoltaic module optimizer redundancy direct connection device. The redundancy direct connection device and the module optimizer are connected in parallel and capable of being installed inside a photovoltaic module junction box or formed into a single module. The photovoltaic module optimizer redundancy direct connection device comprises a power switch circuit and a drive control circuit which controls on-off of the power switch according to received signals from the module optimizer, enables the redundancy direct connection device to be shut off during working in the module optimizer and imposes on influence on the maximum power point tracing of the module optimizer. When the module optimizer fails, the redundancy direct connection device enters the direct connection mode, enables the failed photovoltaic module to work ordinarily and increase reliability of the photovoltaic system.

Description

Technical field: [0001] The invention belongs to the technical field of photovoltaic power supply, and in particular relates to a photovoltaic module optimizer redundant direct device and a control method. Background technique: [0002] As the global energy shortage becomes more and more serious, renewable energy is being used more and more widely. In recent years, photovoltaic power generation, as a green energy with broad prospects, has become a research hotspot in domestic and foreign academic and industrial circles. One of the emerging industries. With the promotion and application of large-scale photovoltaic power generation technology, how to make the photovoltaic power generation system generate electricity more stably and effectively has become a problem that we are more and more concerned about. [0003] The existing photovoltaic power generation system uses multiple photovoltaic modules connected in series and then connected to the inverter to output electric ene...
